HENRY B. MORRIS, OF ITHACA, NEW YORK, ASSIGNOR TO THE AUTOPHONE COMPANY,OF SAME PLACE.

MACHINE FOR MAKING AND INSERTlNG STAPLES lN MUSIC- ROLLERS.

SPECIFICATION forming part of Letters Patent No. 339,679, dated April13, 1886.

Application filed October-8, 1885. SerialNo. 179,371. (NomodvLl York,have invented a certain new and useful machine for inserting wire camsor staples at predetermined points into rollers intended for use inmechanical musical instruments, of which the following is aspecification.

The leading characteristic of the machine is an intermittently-inovingpattern which governs the insertion of the staplesand determines theirlength.

As is well known, the shortest notes of such mechanical musicalinstruments as hand'orguns, orchestrions, 850., are produced by singlepins projecting from the surface of a slowlyturning cylinder, whichoperate upon keys or valves to produce the tones. V Longer notes must bemade by cam-surfaces upon the roller, of suitable length, so as to holdthe keys or valves open for the proper time. Such a cam is commonly madeof a wire bent into the form of a staple, its two points being insertedinto the roller, and its middle projecting part being concentric withthe surface thereof. The preparation of such staples of many variouslengths and their correct insertion into the roller isa work requiringmuch labor and skill, and rollers so prepared are very expensive.

The object of this invent-ion is to provide mechanical means for makingsuch staples and for driving them into the roller automatically andwithout the intervention of skilled labor.

In order that my invention may be clearly understood,l have illustratedand will proceed to describe a practical form of a machine adapted toinsertstaplcs in a wooden roller along a spiral line.

Figure l is a plan view of the machine. Fig. 2 is a verticallongitudinal section in the plane indicated by the broken line 1 1 ofFig. 1. Figs. 3 to 10 illustrate details of the machine, some beingdrawn on a larger scale than Figs. land 2-, and others on the samescale. Fig. 11 is a plan view, partly in section, of the roller-canriage and its attachments, the section being taken upon the dotted line2, Fig. 2.

The sameletters of reference indicate identical parts in all thefigures.

The various parts of the machine are mounted on a suitable bed-plate ortable, A, provided with the shear a across one end, for the support andguidance of the rear side of a sliding carriage, consisting of theupright cheek-plates B B and the parallel connectingbars B B B. Thefront side of the carriage is supported and guided by the bar 0,parallel with the shear a, said bar passing through holes in thecheek-plates B B, and being itself supported and held by the lugs O C"on the bed plate A, into which it passes. A horizontal roller, D,provided with projecting hubs at its ends, is arranged in suitablebearings between the cheek-plates of the carriage, 6 5 said hubsprojecting through the cheek-plates B B and forming the journals of theroller. The parts of the hubs passing through the cheekplates aresmaller than those adjoining the roller, thereby forming shoulders uponsaid hubs, 7c which prevent any lateral motion of the roller bet-weenthe cheek-plates. The hub D projects beyond the cheek-plate B, and uponits outer end is rigidly attached the spur-wheel E. A shaft, F,journaled in the fixed bearing F on the bedplate, passes through the hubD into roller D, which is bored nearly its whole length to fit theshaft. A keyway, f, is cut in that part of shaft 13 which passes intothe roller and hub, and the hole through which it so passes is providedwith a corresponding spline, so that while said roller is turned by theshaft it may, with the carriage and the spurwheel E, move longitudinallythereon. The hub at the end opposite that entered by shaft 8 5 F istapped or provided with a fixed nut to fit upon the screw H, whichpasses through, the hub into the roller nearly far enough to meet theend of shaft F. The outer end of the screw is rigidly secured to astandard, H, on the bed-plate A, or it may be so arranged as to befastened and loosened at pleasure, so that the IOllvl and carriage mayhe slid along the ways by revolving the screw when the machine is atrest. Two rings, G G, of steel or other 5 hard metal, about equal indiameter to the roller D, are rigidly attached thereto at its oppositeends. The outer surface of the rings is roughened by line flutes formedtherein parallel with their axis. Upon the surface of the rec rollerbetween the rings is formed a deep squareshaped screw-thread, D, of thesame pitch as the screw H. A longitudinal groove, D is also formed inthe roller, extending from ring G to ring G, said groove being muchdeeper than screw-threads D which it intersects. Two parallel bars, I I,are fitted into the groove D and there secured by screwsat their ends,which screw into the roller. The outer surface of bars I I is curved,being flush ar d concentric with the 'top of screw-threads D I is apatter-n-belt, preferably made of a sheet of steel, which tightlyencircles the roller D, and is riveted or otherwise secured by its endsto the bars I l, the body of the pattern-belt resting upon the tops ofscrew-threads D The pattern-belt is pierced with a series of holes,which govern the position and length of the staples to be driven intothe musicroller; hence a separate pattern is required for eachdifi'erent kind of music-roller to be produced,- and said pattern may bereadily changed by unscrewing the bars I 1 removing them with the belt Iattached, and replacing them by another similar pair of bars, to whichis fastened a different pattern-belt. A live-spindle, K, is journaled inthe upper portion of cheek-plate B. This spindle carries a disk, K, atits inner end, and at the opposite end a fixed spur-wheel, L, of thesame diameter and number of teeth as spur-wheel E, which drives itthrough the medium of an intermediate spur-wheel, L. The disk K isprovided with a center pin, and also with a drive-pin,'K Gheelcplate Bcarries in its upper portion a dead-center, K screwed in thecheek-plate, so that it may be adjusted. The wooden roller M, in whichthe staples are to be inserted, and which I term the musicroller, iscentered on dead-center K and central pin of disk K, one end of theroller being bored with an eccentric holeto receive the drive-pin K". Itwill be seen that the turning of shaft F has the twofold effect offeeding the carriage, together with the rollers D and M, and ofrevolving said rollers synchronously, so that they complete a rotationin the same time.

The devices for cutting and forming the staples and inserting them inthe n1usicroller are mounted upon the stand N, erected on the bed-plate.A sliding head, 0, is mounted upon the stand, sliding in a dovetailgroove formed in the top of said stand, in a direction parallel with theaxis of the music-roller. The sliding head carries two sliding blocks,0', O", which are fitted to parallel dovetail grooves in the top of saidsliding head. Said sliding blocks move horizontally in a direction atright angles with the axis of musicroller. A vertical die-plate, P, isrigidly secured to the sliding head 0 on the side nearest themusic-roller. In one side of the dieplate, near the top, is formed anotch whose lower side is horizontal, the upper side being inclined,preferably at about thirty degrees to the lower. zontal ledge of metal,p, on one side, the upper side of which ledge is even with lower side ofnotch.

Attached to the sliding block 0', is a tri angular punch, P, two edgesof which fit the notch in die-plate P. The wire R, to be made intostaples, is fed from a reel overhead, vertically downward, by a pair offeed-rolls; R R, mounted upon a standard, R erected on the bed-plate,said rolls being driven through the medium of a pulley, R, and a belt,by a pulley on the shaft 3. The feedrolls do not press verytightly uponthe wire, so that when its advancing end strikes the ledge 19 itsfurther progress is for the time prevented, the rolls revolving withoutadvancing the wire, which, to prevent it from being bent, may, whennecessary, be conducted through a small guide-tube nearly as far as theupper sideof the notch in the die-plate. The sliding block 0 is providedwith a transverse dovetail groove near one end, inwhich a block, 0,slides horizontally, said block having a swageplate, O",'rigidlyattached to it. One end of the swage'plate projects nearly across theface of punch P, and is beveled at same angle as the punch and notch indie-plate. The end of the punch is recessed to receive Plate P isprovided with a horithe swage-plate, the bottom of said recess beingcurved, as is also the swage-plate, to the shape required to make thestaples concentric with the music-roller when driven. The normalposition of swage-plate is in about the same plane as the die-plate P.

The process of forming and driving astaple is as follows: WVhen theblock Ois moved forward, the punch P cuts off the portion of wireextending across the notch in die-plate, pressing it at the same timeagainst swageplate 0, to prevent it from flying away. The furtheradvance of the punch causes the swage-plate O" to force the wire backinto the recess in the face of the punch, bending it into the requiredshape, as is fully shown in Fig. 8. The staple is firmly held betweenthe swageplate and punch, which advance together toward themusic-roller, the block 0 being now driven by block 0' by means of studO rigidly attached to block 0, and projecting into a slot in the side ofblock 0 said slot and stud being so arranged that the block 0 shallbegin to movejust as the staple has been formed between the punch andswage-plate, in the manner just described, and also that the block 0shall not be withdrawn beyond its normal position by the retreat ofblock 0'. When the staple has been advanced so far that its ends haveentered the wooden roller beyond danger of its escape, the swage-plate Ois suddenly withdrawn by means of the lever O centrally pivoted on block0, havingone end engaged with sliding block 0 and being actuated by thestationary pin 0 upon the head 0, which pin is struck bythe outer curvedend of the lever as the same advances with its block 0. The punch I nowcontinues its advance until it has inserted the staple to a certaindepth into the music-roller, when it is withdrawn by retreat of block tothe place of beginning, the swageplate 0, block 0, and lever O returningto their normal positions, being influenced by the spring 0*, attachedto block 0" acting upon the lever. More wire is now advanced by thefeed-rolls and the punch is ready for another stroke. It should beremarked that the block 0' slides rather tightly in its groove, thuscausing suffi cient pressure between the swage-plate and punch to insurethe bending of the wire into the staple required. Since the wire is fedby the feed-roll always in the same line, and all the staple-formingdevices above described may be moved laterally by sliding the head 0,which carries them, it follows that wires of different lengths may becut by the beveled punch P and its corresponding die, depending fortheir length upon the position of sliding head 0, and as the swage-plateO is also beveled the shanks of thestaples when formed will all be ofequal length, so that their outer curved portion alone will vary.Moreover, if the head 0 remain stationary after the wires are cut andwhile the staples are being driven, they will always be driven into theroller in the fixed plane of the feed-wire R.

1 will now proceed to describe the means whereby the insertion of thestaples is governed by the perforated patternhclt. A line of shaftingextends across the end of the bedplate opposite the rollercarriage,being suit ably journaled in standards erected upon the bed-plate. Thisshafting consists of two independent portions, S S, arranged in the sameline, their place of separation being indicated by the dotted line S",Fig. 1. At the junction of the shafts S S is a clutch consisting of adisk-plate, S, fixed upon the end of shaft S, i

, loosely upon the roller-shaft F, and having large central hub, X". Thehub X is confined and upon shaft S a larger circular plate, S", providedwith an overhanging flange which encircles dislnplate S. A block, 'l,moves radially in a groove in the outer side of plate S being forcedoutwardly by an ellipticspring, T, acting against a pin, T", fixed inthe block. A radial notch, T, is out through the flange of plate S, sothat when block T is pushed outward by the spring it enters notch T andlocks the plates together, causing them to re volve as one. The shaft Sand plate S are revolved continuously by suitable motive power appliedat the opposite end of shaft S, but

, shaft S remains at rest when the block T is forced centrally andprevented from engaging the notch. T. clutclrbar T centrally pivotedupon a stand ard attached to the bed-plate and operated by meanshereinafter to be explained.

The clutch-bar T oscillates vertically and bears downward upon the pinof clutchi block T, so that when said bar is in its normal position, asshown in Fig. 3, the block is prevented from engaging with slot T As theblock T revolves, being carried around by disk S", its centrifugalmotion is prevented during This is effected by the.

most of its course by the overhanging flange of disk 5*; but when itarrives near the top the bar T, acting upon pin T forces the blockfarther in toward the center of disk than is needed to prevent itsentering slot T hence the bar 1 may be elevated to a certain distancewithout allowing the clutch to lock. At each revolution of disk S a cam,S fixed thereon strikes a pin, T, on bar T, thereby depressing the barbeyond its normal position and immediately releasing it. The clutch-baris connected at its opposite end by the vertical connecting-rod U withthe rock-arm U, attached to rock-shaft U". Another rock-arm, U", isfixed upon said rock-shaft diametrically opposite U, and is connected bymeans of vertical connecting-rod U with the l'eeler-bar V, near themiddle of said feelcr-bar. A standard, W, is erected on the bed-plate,to the upper part of which one end of feeler-bar V is pivoted, so thatsaid bar may oscillate vertically.

Rigidly attached to the feeler-bar near its free end is the feeler,consisting of a short cylindrical bar, V, preferably of hardened steel,having upon its lower end a smaller cylindrical part, V which I call thepoint. WVhen the machine is not inserting staples, the point V restsupon the pattern-belt I on roller D, beingpressed downward by a spring,U on the bed-plate, which acts upon lower end of rod U, and through itinfluences the feelerbar V and all its connections just describednamely,rock-arms U U, roek-shaft U rod U, and clutch-bar T". This mechanism isso arranged that when the point V is resting upon the pattern-belt theclutch'bar is in its normal position, Fig. 3.

Upon the continuously-revolving shaft S is asmall tight pulley,X,whichtransmits motion by the belt X to a large pulley, X turning between twocircular friction-plates, F and F upon shaft F, plate F being rigidlyattached to shaft, and plate F, fitting loosely on the end thereof,being prevented from turning on the shaft by a spline. The hub X" isCOID- pressed between frictionplates by means of a cupped spring, F",held and regulated by a screw passing centrally through said spring intothe end of shaft F". Friction is thus produced between the hub andfriction-plates suf ficient to cause shaft F to be turned by pulley X",except when otherwise prevented.

The perforations in the pattern-belt I consist'each of a narrowparallelsided slot, J, of predetermined length, terminating in a largecircular hole, J. Said perforations are so located as to be directlyover the grooves between the screw-th reads D of the roller D.

As before explained, the screw-threads 1) formed upon the surface of theroller D, are of the same pitch as the fecd-sercw H. The feeler-point Vis situated directly over the spiral groove between the screwthreads onthe roller.

The object of grooving the roller D spirally,

with the same pitch as the feedscrew, is that as said roller is fedalong the screw H by its revolution thereon the screw-threads D shallmaintain their relative position to the feelerpoint V",thegroovebetweentwo ofsaid threads being always directly under the feeler-point. Thiswould not be the case if the threads D were of a pitch different fromthat of the feedscrew. The groove in the pattern-roller being thusalways under the point aifords the latter sufl'lclent depth for itsrequired descent through the holes in the pattern-sheet.

In operating the machine, the shaft F being turned, the rollers D and Mare revolved and the carriage is fed along its guides. The feelerpoint Vrests upon the pattern-belt, describing a spiral course thereon. \Vhenthe feeler encounters a perforation in the belt, the point V at oncedescends into the narrow slot J as far as permitted by the larger part Vabove. The feeler-bar V also descends, and through its connectiontherewith the clutch-bar T is moved, so that the end of clutch-baradjoining the clutch is elevated, not far enough, however, to permit theblock T to engage the slot T; hence the clutch is not yet locked and theshaft S remains at rest. The feeler-bar is provided with a hook, Y, onits under side, supporting a horizontal rod, Y, parallel with the rollerD. The ends of rod Y are attached to two pawls, Y Y, said pawls beingcentrally supported on studs in the cheek-plates of the carriage, whichstuds pass through central longitudinal slots in said pawls. Anotherrod, Y parallel with Y, connects the pawls Y and Y at their oppositeends, the two rods and the pawls thus forming a rigid frame. The ends ofthe pawls adjoining rod Y are adapted to engage the fluted rings G G onroller D. \Vhile the feeler-poiut V rests upon the pattern-belt I thepawls Y Y are held up by the hook Y out of gear with the fluted rings;but when the feeler-bar V is depressed by the descent of the point-intoa slot, J, said pawls, being thus lowered, engage with the flutes insaid rings, and are moved longitudinally by the continued rotation ofroller D, the rod Y striking and driving before it the slotted cam-barZ. This cam-baris provided with a longitudinal slot near one end, whichend is supported by a stud, Z, fixed in standard V. The opposite end ofcam-bar is beveled to correspond with a cam, Z attached to the slidinghead 0, and is supported and held against said cam by a shouldered stud,Z, erected on the bed-plate. When by the progress of the roller D thepoint V reaches the end of slot J, the thicker portion V of the feelerenters large hole J, the point descending into the spiral groove betweenscrewthreads D. This brings the friction driven rollers D and M to astandstill, the additional depression of feeler-bar Vresulting, throughits connections with the clutch-bar T", in looking the clutch and therotation of shaft S. Astaple is now formed and inserted in themusic-roller, the block 0 being advanced and retracted by an eccentric,S, on shaft S, which actuates said block through the medium of theeccentric-rod S, rock-arm S wrist S and connecting-rod S. The wrist S isprolonged so that the engaging-eye of rod S may move lengthwise upon itwhen carried by sliding head 0, the opposite end of rod being snuglypivoted to block 0. When a staple has been inserted, the cam S strikespin T momen tarily depressing it so far that through their intermediateconnections the feeler point V is raised clear above the surface of thepatternbelt, which, being no longer restrained by the feeler, at onceproceeds to revolve. The point V is quickly allowed to drop upon thepattern-belt, and all the parts of the machine connected with it resumetheir normal positions, the sliding head 0 being returned by aspring,'0", upon standard N, and the cam-bar Z by spring W on standardXV. By the eledraws thepawls Y Y from contact with fluted rings G G, andthe pawls are driven back to their first position by the retreat of thecambar.

It is obvious from the foregoing description that so long as thefeeler-point rests upon the imperforate portion of the pattern-belt thefrictioirdriven rollers D and M revolve and the staple-formingdevices-remain at rest also, that the descent of the feeler V into alarge hole, J, causes the rollers to stop and the staple devices tooperate. It is furthermore plain that the entrance of the feeler-pointinto a slot, J, results in sliding the head 0. Since the length of astaple depends on the position of head 0, as before explained, and thisin turn depends upon the distance to which the cam Z and cam-bar aremoved by the pawls Y Y, it follows that the presence of a long slot, J,in the pattern-belt will cause more motion of the head 0 than a shortslot would do, and consequently the formation of a longer staple; hencethe length of each staple will be in direct proportion to the length ofits corresponding slot in the prearranged pattern-belt. The punch P doesnot drive the staples quite to their destined depth in the music-roller,thereby avoiding the danger of driving too far any previously-drivenstaples with which it may come in contact, but all the staples may besubsequently reduced to a proper depth by revolving the music rollerinanother machine against a hardened pressure-roller, or by any otherconvenient method.

In order to perform most pieces of music, single pins are required uponthe music-roller as well as staples. Such pins may beinserted before orafter the staples, either by hand or by automatic machinerysuch, forinstance, as that for which Letters Patent were granted to me April 7,1885, N o. 3l5,0520r the pi n'driving devices therein described may becombined with this machine, so that a roller may be furnished with bothpins and staples by the same machine. This I regard vation of thefeeler-bar V the hook Y with as a mere modification of my invention,and" many other variations may be made withoutdeparting from theprinciples of my invention. For instance, to adapt the machine forpreparing rollers having circular rows of staples and pins, thescrew-feed may be so modified as to advance the carriage a distanceequal to that between two adjacent rows at the completion of each fullturn of the pattern-roller, parallel circular grooves being substitutedfor the spiral grooves in said roller.

I believe that I am the first to provide a machine for automaticallyinserting staples in music-rollers in accordance with apreviouslyprepared and intermittently-moved pattern, and therefore claimsuch machine broadly. As regards the pattern, its form maybe muchvaried. Thus, instead of using a changeable pattern-belt upon a roller,a separate roller may be provided for each kind of music-roller havingdepressions corresponding with the perforations, or the pattern nnyconsist of a plane surface with perforations or depressions, suitablechanges being made in the feeler and other connections.

I claim as my invention 11.. A machine for making and inserting staplcsin music-rollers, organized with an inter n'iittingly'moved pattern,which governs the length and position of the staples, substantially asdescribed.

2. A machine for making and inserting stapics in music-rollers,organized with an intermittingly-inoved pattern, which governs theposition and length of the staples, said pat tern being moved by afriction-feed, SLlbSh2llltially as set forth.

3. In a machine for making and inserting staples in music-rollers, thecombination, substantially as set forth, of the feed-carriage,feed-screw, and pattern-roller, the said roller having its surfacespirally grooved with the same pitch as the feed-screw.

4. In a machine for makingand inserting staples in nuisic-rollers, thecombination, sub stantially as and for the purposes set forth, of agrooved pattern-roller with a perforated pattern-belt, said beltencircling the roller and havingdts perforations opposite said grooves.
